AMD and Intel have gotten much better at pushing the stock CPU frequencies up to the actual process limits as compared to 10 years ago. Also the various Turbo boost features now automatically push it even further towards the limits when there is thermal headroom. Therefore, there is hardly very much headroom left on the table anymore for overclockers.
In 2009 I overclocked my i7 920 from 2.66GHz stock to 4.2GHz fully stable with custom water-cooling. More recently I have used i7 7700k and Ryzen 5950X under custom water-cooling and manual overclocking gets you less than 10% at most. Hardly even worth it. Just keep the CPU cool and let the built in boost features work.

The chiplets in my new Ryzen 7 5800X are so small that even my custom water loop can only do so much with the temperatures as there just isn’t enough surface area for thermal transfer. I was honestly worried that I was repeatedly messed up the mount of the CPU block, thermal paste application, or that one or both were just bad when I fired up HWInfo64 and did a burn-in test; my old Ryzen 5 1600X didn’t get near as hot on a 240MM AIO when overclocked as the 5800X does doing normal boosting on a 360+240mm custom loop.
